Application f led June 12 Thisinventionrelates to improvements in wheelrim locking and contracting ances and the obiectsaof theinvention are toprovide combined rimrlocking andtiro in. normal position: and, on beingcontracted,

is ELHtOll'lflillCflllY locked'in contracted 1)0S1- tion. i

Further objects are to provide a device of struction that canbemanufactured with the rim and at very low cost.

Further objects are to provide, ,in'combination with the locking meansformed on the rim, a tool for operating said means."

With the foregoing and other objects,

hereinafter more fully referred to, in view removing means whereby therimlis locked:

this character of durable and simplified con-" the invention consists ofcombined locking and tool engaging members rigidly mounted in spacedrelationship to one another on the rim and having intern'icdiatelythereof an engaging lug or the like designed, in normal position, tolock with one of said members, the members so looked being designed, onthe rim being contracted, to automatically engage with the other lockingmember to engage with a rim contracting tool whereby the rim iscontracted to bring the locking members together and lock them. ,1

Referring now to the drawings in which like characters of reference,indicate correw sponding parts in each figure:

deferring now more particularly to the drawings 11]? which apreferredexample of my invention is illustrated, 10 designates a 'tirefrim of wellknown constructionand of any suitable material.

This rim is' transversel-y' sides also orifices 16in said sidesregistering with one another and designed, as

hereinafter more fully explained, to engage with a rim contracting tool.,This plate or split at 11 and has rigidly scoured adjacent one of theends, 'asat 12, 21 channelshaped plate 13 open at both ends and formediwith opposing recesses 14 in the combined rim lockingand toolengaging"member. 1.3 p1'ot'rudes beyond the end 17 of the rim and is providedfwith an opening 18 in the bottom and, spaced therefrom,a secondopening or slot 19 with an overlapping lip 20 adapted to engage, ashereinafter more fully referred to, with. the handle end of thecontracting tool whereby the member 13 is prised or raised up out ofengagement.

Across the split 11 and adjacentthe other end 21 of, the rim is a lug 22formed with a transversely extending lip 23ion one side and a slot 24 onthe other side. This lug is designed to engage with and lock in theopening 18 in the member 13, seeFigure 1,

the lip 23engaging with the end of the openinglS to positively lock thelug therein while, for further retaining it in the opening 18 andpreventing side movement, I provide a locking member 25 pivotallymounted zit-26 in the member 13 and designed to engage in operativeposition with theslot 24s on the rim 1O is r base of this member extendsbeyond the sides 29, as at 30, and is formed with a transverselyextending groove or channel 31 in which is pivotally mounted a link 32bent downwardly as at 33 at its outer end. This link member, asillustrated in Figure 2, is designed, on the rim 10 being contracted bymeans of the tool 34,'to automatically engage with the opening 18 in themember 13 and lock the rim in contracted position.

The tool i-A consists of alever arm 35 bent adjacent its outer end, asat 36, to form a prising or raising means to engage with the lip 20 inthe member 13 to unlock it by litting it. out oi? engagement with thelug For contracting the rim the arm is pro vided, at its outer extremityas at 37, with an arm or rod 38 pivotally mounted and bent substantiallymidway of its length at rightangles as at 39. A second arm, spaced fromthe arm 88, is also pivotally mounted in the arm 35, as at 40, and isbent at right angles to itself and to the arm 35 as at ll. The bentportions 4:2 and 430i the pivotally mounted rods in the arm 35 aredesigned, as

illustrated in Figure l, to simultaneously engage with the orifices 28in the member 27 and with the orifices 16in the member 13 so that, onthe arm 35 being manually operated, the rim is contracted to theposition illustrated in Figure 2.

As many changes could be made in the above construction and manyapparently widely different en'ibodimcnts oi? my invention, within thescope of the claims, constructed without departing from the spirit Thehooked link 32 is then automatlcally engaged and locked in the orscopethereof, it is intended that all matter contained in the presentspecificatlon and accompanying drawings shall be inter- 3e preted. in anillustrative and not in a limiting sense.
